Figure 5. The PL lifetime mappings of single (A) BiVO4 and (B) 3Au/BiVO4 particle beforer and after adding TC solution to the reaction vessel; The τav with decay rate on representative points of (C) BiVO4 and (D) 3Au/BiVO4 particle in air and after adding TC solution; (E) PL intensity of Point 1 and Point 2 over BiVO4 and 3Au/BiVO4 particle before after adding TC solution. PL: Photoluminescence; BiVO4: bismuth vanadate; TC: tetracycline.
